Definitions
- the present invention provides a method and a test composition for the determination of bydrogen peroxide using a novel chromogen as a hydrogen donor. More particularly, it provides a method for the determination of hydrogen peroxide by reacting hydrogen peroxide with the chromogen in the presence of peroxidase and determining the pigment formed,and test compositions suitable for the determination.
- the determination of a substrate was generally carried out by oxidizing the substrate by the action of oxidase and determining the formed hydrogen peroxide.
- uric acid is oxidized by urioase
- choresterol is oxidized by choresterol oxidase to form hydrogen peroxide.
- the hydrogen peroxide is determined by reacting the hydrogen peroxide with a chromogen in the presence of peroxidase to form a pigment and measuring the absorbancy of the reaction solution coloured by the formation of the pigment in the visible ray region.
- substituted amino means mono- or disubstituted amino and the substituents are alkyl, alkenyl, aryl, hydroxyalkyl or acylalkyl.
- the raw materials are known pigments.
- the raw material is subjected to reduction in the presence of reducing agents such as NaBH 4 , Fe-HCl, etc.
- the reduction is carried out in a solvent such as water, methanol, acetone, etc. at from room temperature to the boiling point of the solvent used.
- the reduction product is isolated from the reaction mixture.
- an acylating agent an alkylthiocarbonylating agent, ester of isocyanic acid, or ester of isothiocyanic acid.
- the reaction is usually at from room temperature to the boiling point of the solvent used.
- the isolation of the desired product from the reaction mixture is carried out by a suitable organic synthesis isolation means such as extraction, concentration, chromatography, recrystallization, filtration, etc.

- a test solution containing 20 ⁇ l hydrogen peroxide solution and the absorbancy of the coloured reaction solution (E) is measured at maximum absorption wave-length ( ⁇ max) of the pigment formed.
- the blank absorbancy (E B ) is measured by repeating the same procedures as described above except that water instead of hydrogen peroxide solution is used.
- the stability of colour is determined as follows. The value of (E-E B ) immediately after the reaction is discontinued (in about 30 minutes) is measured. Then the reaction solution is further incubated at 37°C for 4 hours and then (E-E B ) is calculated.
- the .symbol “ ⁇ ” means that the decrease of the value of E-E B is 0-5% during the further incubation and "+” means that the decrease is 5-10%.
- the maximum absorption wavelength in the visible ray region of the pigment is larger than that of hemoglobin contained in serum, which is around 400 nm and therefore, the absorbancy by the present method is not affected by hemoglobin.
- the compound (I) or (II) and POD may be added to the system where hydrogen peroxide is produced (hereinafter referred to as "H 2 O 2 -producing system").
- the absorbancy of the reaction solution coloured by the formation of pigment is measured in the visible ray region, 400-760 nm.
- the standard curve showing the relation between the amount of hydrogen peroxide and absorbancy is prepared by using a standard hydrogen peroxide solution as the sample. The amount of hydrogen peroxide in the sample is calculated by applying the absorbancy obtained to the standard curve.
- the reaction is usually carried out at a temperature of 5-50°C, preferably 25-40°C, in a buffer solution having a pH of 2-10 and completed in several minutes.
- phosphate buffer tris-HCl buffer, succinate buffer, citrate buffer, acetate buffer, etc. may be used in a concentration of 0.005-2 mol/l.
- the present method may be used for the determination of reactants in a, system where hydrogen peroxide is produced.
- a, system where hydrogen peroxide is produced Particularly, when the system is an enzymatic reaction, both the H 2 O 2 producing system and the system where pigment is produced [hereinafter referred to as pigment-producing system] proceed at the same time and therefore, such a method is simple and convenient.

- the substrates of these enzymatic reactions are contained in serum, urea, etc. and the determination of the substrates is useful for diagnostic purposes.
- Another aspect of the present invention is to provide a test composition for the determination of hydrogen peroxide which comprises oxidase for the substrate to be determined, the chromogen represented by the formula (I) or (II) and peroxidase.
- the composition may contain buffer reagent.
- composition may contain surfactants such as polyoxyethylenealkylether, antiseptics such as sodium azide, ascorbate oxidase for decomposing ascorbic acid, etc. if necessary.
